Detroit & Lima Northern 2-6-0 "Mogul" Locomotives in the USA


Class Details by Steve Llanso of Sweat House Media

Class 61 (Locobase 16468)

Data from James Dredge, A Record of the Transportation Exhibits at the World's Columbian Exposition (New York: John Wiley & Sons, 1894), p. 123, and Plate XXIX). See also DeGolyer, Volume 18, p. 195. (Thanks to Chris Hohl for his 13 January 2020 email and well-drafted spreadsheet, the latter noting the absence of this locomotive from Locobase and providing detailed data.) Works number was 13405 in April 1893.

This seems rather a mundane example of Baldwin's work to show at the 1893 Columbian Exposition in Chicago, but there it was. And maybe that was Baldwin's point: we don't have to dress up to look good. After the exposition ended, Baldwin sold the engine to the LN as their 61.

Baldwin supplied four more Moguls (works numbers 14670-14673, road numbers 62-65) with the same cylinder dimensions in January 1896. Locobase hasn't determined if this a repeat of the 61's order.

If longevity is any guide, 61's 34 year career with the LN and successors Detroit & Lima Northern, Detroit Southern, and Detroit, Toledo & Ironton suggests that Baldwin made a good case.
